Always support float128 on ia64 (PR target/77586).
Bug 77586, and previously
<https://gcc.gnu.org/ml/gcc-bugs/2016-08/msg03233.html>, reports
ia64-elf failing to build because of float128_type_node being NULL,
but being used by the back end for __float128.
The global float128_type_node is only available conditionally, if
target hooks indicate TFmode is not only available as a scalar mode
and of the right format, but also supported in libgcc. The back-end
support, however, expects the type always to be available for
__float128 even if the libgcc support is missing.
Although a target-specific node could be restored in the case where
libgcc support is missing, it seems better to address the missing
libgcc support. Thus, this patch enables TFmode soft-fp in libgcc
globally for all ia64 targets. Support for XFmode in libgcc (that is,
for libgcc2.c XFmode functions, not soft-fp) is also enabled for all
ia64 targets so that ia64 no longer needs to define the
TARGET_LIBGCC_FLOATING_MODE_SUPPORTED_P hook.
I've confirmed that ia64-elf builds cc1 with this patch and it passes
-fself-test. I have not otherwise tested the patch. It's plausible
that ia64-elf and ia64-freebsd might work as-is, but ia64-vms probably
needs further changes, by someone familiar with VMS shared libraries,
to implement an equivalent of ia64/t-softfp-compat in that case
(avoiding conflicts between __divtf3 from soft-fp and the old alias
for __divxf3).

During the lowering phase, the variable arguments to a varargs call are
packaged up into a temporary slice object; the storage for this slice
was being unconditionally allocated on the heap. Heap allocation is not
necessary, however, if the varargs call correspond to an "append", since
the append runtime routine only reads the slice storage (as opposed to
stashing away the storage pointer). Enhance the lowering code to keep
the slice storage on the stack for append() calls, to improve
performance.
